ChronoCalc vs Pressurisation

ChronoCalc is designed to streamline all your time calculation needs. - If I start work at 8:40, and end at 4:25, how much time has passed? - What time will it be in 5 and a half hours? What time was it 5 and a half hours ago? - If I watch 8 episodes lasting 43 minutes each, how much total time is that? - How many hours are 143 minutes? Features: - Addition, Subtraction, Multiplication, and Division - Subtract From operator lets you enter start times before end times - perfect for long lists of calculations - Millisecond precision - AM, PM, and Military/24h time - Intervals can be entered as H:M:S:MS or as decimals - Activity Timer makes it easy to get the elapsed time between the start and end of an activity - Easily convert between hours, minutes, seconds, and milliseconds - 6 different color schemes to choose from

Transform Your Flight Experience with Advanced Cabin Monitoring Cabin Pressurisation is your companion for understanding and visualising how aircraft cabins are pressurised at altitude. Whether for training, education, or curiosity, this app brings complex systems to life with authentic cockpit-style instruments and intuitive displays. Cockpit Modes (Tailored to Aircraft Types): Advanced EFIS – State-of-the-art display (max 9.0 ΔP) Turboprop – For smaller turboprop aircraft (max 5.5 ΔP) Corporate Jet 8.6 PSI – Inspired by a renowned business jet (max 8.9 ΔP) Corporate Jet 10 PSI – Modelled after the fastest business jet (max 9.6 ΔP) Airliner Legacy – Classic jet airliner design (max 9.1 ΔP) Airliner EFIS – Modern jetliner interface (max 8.6 ΔP) Key Features: Cabin Altitude Gauge (CABIN ALT) – Displays cabin altitude in thousands of feet. Differential Pressure Gauge (ΔP) – Shows the pressure difference between cabin and outside air. Variometer (CABIN CLIMB) – Tracks the rate of cabin altitude change. Ground Speed Display – Monitors ground speed in knots. Limitations: GPS Dependent – Best performance when your device is near a window. Mach Indicator – Approximate only (based on ground speed and altitude). Important: This app is designed for educational purposes only. It is not a substitute for certified aircraft systems or instruments.
